Who cares? I don't pronounce Russia as Rooseeyah like a native Ruskaya from Mat Rodina would. I don't pronounce Austria Oeste-rike.Why should I pronounce Saiga as a native Russian would? The English pronunciation of that word would be Say-ga .

Nalioth and Lunyfringe are right. Every time I went into a gun shop and asked about SAIGA'S - They said "You mean Say-ga's?" So, I asked two of my Russian friends..... They both said it was pronounced Sigh-ga and they were both familiar with the guns.
